Trade wars are easy to win (When you run a huge trade deficit).
But FED wars. Those are hard. The best you can do is constantly harp on the FED and tell them publicly what they should do, and then point to them when the economy stumbles and they didn’t do what you told them they should do.
But you still should not refer to the Chairman of the Fed as an enemy.
The FOMC did not have a meeting today. Trump just got confused.
